METHOD OF AND MEANS FOR TRANSLATING SOUNDS.

Application filed April 16, 1914, Serial No. 832,219.

To all whom it may concern: Be it known that I, RAY E. HALL, a c tizen of the United States of America, resid- .ing at Portland, in the county of Multnomah, in the State of Oregon, have in vented certain new and useful Methods of and Means for Translating Sounds, of which the following is a specification,- refer ence being bad to the accompanying drawings.

This invention relates to a method of and apparatus for translating sounds. particularly those produced in the receiving apparatus of wireless signaling devices, into mechanical movements to and fro, each corresponding in duration to the duration of the individual sounds produced.

\Vireless signals are commonly detected and received by the use of a receiver worn by the operator adjacent the ear. The sounds produced by wireless receivers are generally so faint that the operator is subjected to a considerable nervous strain to detect all signals and messages and it has been found necessary in some instances to locate the receiver in a sound-proof room where absolute quiet is constantly maintained. Even with such precautions messages are sometimes unintelligible because of their faintness.

It is an object of my invention to provide a method of and apparatus whereby the sound waves set up by the diaphragm of a wireless receiver are automatically translated into mechanical movements to and fro, which may actuatesuitable indieating devices to produce signals corresponding'to these movements and of such magnitude that they are readily perceptible.

Other objects and advantages of my invention Will be apparent as it is better understood by reference. to the following specification when read in connection with the accompanying drawing, in which- Figure 1 is a vertical section through a translating device, in which the sensitive jet is shownin disrupted form; Fig. 2 is an enlarged sectional view of a portion'of the same apparatus, showing the jet directed through the opening in the vane, and Fig. 3 is a plan view of the vane.

Referring to the drawmg,

to direct a jet 1 of the fluid into the chamher 2, formed by the sound-proof casing 3,

chamber 5, communicating with the chamher 2, and a lever 6 is pivotally mounted at 7 on the bracket 7 near the junction of the two chambers. The end of the lever 6, extending into the chamber 2, is provided with a vane S of an area substantially equal to the cross-sectional area of the chamber 2. The vane 8 is provided with a central orifice 8" disposed, as indicated in Fig. 2, in the path of the fluid jet.

The opposite end of the lever 6 extends into the chamber 5 and is adapted to cooperate with a contact 9 to close the electrical circuit 10. containing a source of electrical energy 11, and an indicating device 1'2,which may be a relay or anyother suitable form of signaling mechanism. A lever 6 is normally biased by a spring 6, disposed be tween an arm of the bracket 7' and the lever, to the position indicated in Fig. '2, in which the lever engages the contact 9.

A funnel is disposed through the casing 3 of the chamber 2, eXtending from a sound producing device, such as the wireless re ceiver 14. having a sound producing dia-, phragm 15 adapted to be actuated by variations of magnetic force of the magnet 16, when electrical impulses are received thereby, to a point adjacent the discharge orifice 17 of the nozzle 1.

The sensitive fluid jet is adapted to assume varying phases. involving relatively gross changes of form, when subjected to sound "ibrations. Figs. 1 and 2 of the drawing represent two phases of the jet and it will be readily understood that the term phases as employed by me doesnot comprehend the minute variations in form,

comprising the condensation and rarefac- 1 indicates a era not'utilize the jet to transfer sound waves per 86.

The normal phase of the fluid jet, according to the usual operation of the device is indicated in Fig. 2, in which the jet is directed through the orifice 8-. the lever 6 being biased by the spring 6 to engage the contact 9 and close the electrical circuitild.

cated in Fig.- 1, and since it can no longer pass through the orifice 8 the force of the jet is directed against the vane 8 and the lever 6 is turned about its pivot 7 against the action of the spring 6, breaking the circuit at contact 9. The disruption of the jet continues for a period equal in duration to the duration of the sound produced by the diaphragm 15 and assumes its normal phase as the sound ceases. immediately moves the lever 6 to again close the circuit at 9. i j

It is to be understood that the phases of the jet do not necessarily operate in the oider described, since under certain conditions of pressure the jet may assume a normal phase, such as indicated in Fig. 1, and assume that indicated in Fig. 2 when sound waves impinge upon the jet. The operation of the vane in this case is identical with that previously described.

It will be readily understood from the foregoing description that I have devised a method and apparatus whereby the constant nervous strain under which wireless operators work is eliminated. In the preferred embodiment of the invention the indicating device 12 is a relay, which closes a local circuit to-suitable indicating media. The indicating device 12 may, however, be utilized as a sounder, whereby the sounds produced by the diaphragm 15 are reproduced in an amplified form or may be simply a device to call the attention of the operator to the fact that a message is being received by the apparatus.

It will be obvious that various changes may be made in the form, construction and arrangement of the parts without departing from the spirit and scope of the invention or sacrificing any of its material advantages the form hereinbefore described being merely a preferred embodiment thereof.
